Unless you are planning to do a lot of off road driving I would not bother with a different carburetor, there is very little difference between the two anyway and all Holley carburetors can be modified for off-road use.

I’d go with the 670 personally…..Be aware that unless you are taking advantage of the truck avenger for the off road related performance it does lack in certain areas for an all around carb. They are all jetted very rich out of the box so a key change is almost mandatory, and there is a slight off idle dead spot that can never seemed to be tuned out….I have 2 of them and while they do what they are meant to do there are better all around carbs.

I've been doing a lot of research and it looks like the holley 670 is good for off road but no good for general driving and the 770 that is in it is probably too big and will guzzle gas, so know I am thinking of going fuel injection. I believe you said you had already done this to your truck and wanted your opinion... Thanks, -J

Fuel injection is definitely the way to go if you want trouble-free performance and driveablity, there's several self-learning fuel injection kits available that bolt in place of a carburetor like the Holley Sniper I'm running, night and day difference from the old carburetor I'd been running for the last twelve years.

The Holley Sniper EFI on my truck, installation is very straightforward, the fuel return line is the hardest part of most of the conversions I've done.

So long as you use the correct throttle arm like the one on my truck there won't be an issue with the kick down cable conversion. Actually it would probably be fine without the arm as it's setup for the GM style kick down out of the box.

A base Sniper 650 is what I'd recommend, good for up to 650hp but happy on a stock engine as well.

I'll also suggest a progressive linkage kit as the stock synchronized four barrel is too touchy for most, and may be too much for a shockish 360 to handle at low speed.

For the fuel system I'd swap to a factory EFI gas tank, '88-90 or '91-93 will work, I've found the perfect fuel pump for this conversion using the early tank, it probably would work in the later sending unit as well but I've not tested it yet.

Thanks everyone for the help, I am currently saving for the Sniper 650 EFI system (thx 440 4spd Power Ram) and keeping the Street Avenger 770 in the beast, I am planning on moving the oil cooler and replacing the lines with braided steel with AN fittings (thx Elwenil), putting a seperate battery with an isolator for all the stuff that was put on there, moving/replacing the heator core pipes to what should be there, and possibly putting the ac unit back in that was ripped out... did I miss anything?

The A518 was renamed the 46RH to comply with federal regulations, to tell if it's a lockup converter or not look at the plugin at the rear of the case, two wire is non-lockup and three wire is a locking converter. Both are four speed overdrive transmissions, the lockup does feel like another gear but is not a actual 5th gear.

Edited as I typed RE instead of RH as intended.
The transmission is low on fluid and was wondering if there was a preferred fluid for the 46RH transmission, thanks for any help in advance...
